Cameron Grant f637a36cfd don't flag the playback hardchan as busy on devices with only one of them.
if a device has vchans already but they are all busy, allocate another one
at open() time, up to a maximum of hw.snd.maxvchans.

when creating/destroying vchans, don't make/remove a devnode for the
first/last one as it replaces a hardchan.
